locations of savanna's

I am researcing the locations of savanna grasslands,
these are some I found allready:

• Brazil - Cerrado Savanna = One of the biggest savannas in brazil with some really tall trees
• Portugal - Alentejo Savanna = Has a very big dry grassland with alot of trees
• Mediterranean Savanna = jungled with trees sadly not so much grass
• Sahelian Acacia Savanna = mostly dry with dead bushes but few trees
• Canada - Wisconsin Bur Oak Savanna = A tall oak wooded savanna
